Hank enlists Nick's help to fix a past mistake and save a man's life while Juliette questions her feelings for Renard.

In a nod to "The Twilight Zone" episode "To Serve Man," "Grimm" offered up a man-eating horror story of its own as Hank (Russell Hornsby) and Nick (David Giuntoli) raced against the clock to save a death row inmate.

Now that Hank is aware the world is full of monstrous human-hybrid creatures known as "Wesen," he started wondering if that guy he put away seven years ago for shooting two men he claimed were cannibal monsters might have been telling the truth, after all. It's an interesting idea, that people are wrongly accused of killing Wesen when they are merely acting in self-defense. Also interesting is the idea that notorious cannibal killer, Jeffrey Dahmer was a Wendigo, a man-eating Wesen.

This case presented a unique challenge for the detectives: proving a man was attacked by monsters without actually calling them "monsters." That the Kreski brothers were cannibals made the job a bit easier. Aside from transforming into fanged grotesques whose breath wrecks of burnt flesh, they left plenty of evidence of their crimes behind.

With only thirty-six hours until Craig Ferren, the man accused of killing Miles Kreski and shooting his brother, John, faced execution, Nick and Hank worked swiftly and successfully to uncover the surviving Kreski's cannibal habit. With Ferren about to be dosed with a lethal injection as Nick fought off Kreski, this one was a real pulse-pounder. But why is that all cannibals listen to classical music while preparing their meals? Once in a while, I'd like to see someone mincing brain meat to a little death metal.

This week's case a good one but the real meat, if you'll pardon the pun, of this episode was in the Juliette/Renard side story. Poor Sean (Sasha Roiz) woke up with a hangover, next to a bottle of booze which he was probably dreaming was his beloved Juliette. Whatever kind of love voodoo Adalind, her mom and her cat cursed these two with, it's bad.

She's supposed to love Nick, whoever he is, but instead Juliette (Bitsie Tulloch) finds herself increasingly enamored with Renard, Nick's boss. Both are desperate to fall out of love with each other and thus, Renard makes an appointment at the Wesen Rite-Aid, Rosalee's (now Monroe's?) spice shop.

It seems Rosalee (Bree Turner) is still "taking care of her aunt" and won't be back until "Grimm" returns mid-season. Not sure what's up with that, but having a newly arrived supporting character suddenly sidelined is disappointing. Especially since things were getting pretty hot and heavy between she and Monroe.

It took some convincing, but Renard gets Juliette to agree to go with him to the spice shop and have their hearts untangled. But not before one last makeout, in front of Monroe (Silas Weir Mitchell). I'm pretty certain Juliette has never been to the shop, but I know Monroe's been to the police station. However, I don't think he's met Renard.

Which means next week's fall finale should see Nick (and us, patient viewers) finally find out what's up with Renard. It was hard enough the first time, but Nick came close to again telling Juliette he's a Grimm, but fear of further messing with her already messed up head didn't seem like a good idea.

Though Juliette may get her memories back, it looks like the story is about to take another exciting turn after Nick came out of the Grimm closet to Hank. This season's done a great job of building up to another big reveal or two and hopefully, next week's episode follows through. The "Juliette amnesia" storyline has run its course and it's about time Renard face some exposure. At the very least, Monroe should be able to put two and two together. And with Adalind set to return to Portland, plenty of hell should break loose as we close out the first half of the season.

In the meantime, "To Protect and Serve Man" offered up one of the smarter cases this season, as Hank was able to recognize a past mistake thanks to his newfound awareness of the Wesen world. And the situation between Juliette and Renard ended up at Monroe's doorstep. Just how tragic their love is we'll have to wait until next week to find out.
